25 Hour Endurance Racer at Factory Five

Team Boothman’s Car Arrives at Factory Five for Upgrades

Factory Five’s favorite son Mark Dougherty delivered old #85 yesterday and turned around
and made a b-line for Pennsylvania so he could attend the Carlisle Import and Replicas show.

Ed Boothman’s dark green Challenge Car arrived here the other day for some race upgrades. The car last ran at the 2010 NASA 25 Hours of Thunderhill road race last December and is slated for races at Virginia International Raceway this July. The tech guys here are going over the car and prepping it for the season.

Amazingly, this car has competed in 4 (!) 25 Hour endurance races (bragging here) and is an amazing testimony to the degree to which Factory Five cars are raced and have been proven over the years.

Team Boothman Racing and the 375hp Challenge car ran the fastest actual lap time of the FFR cars at 1:54.692!
The car had a constant stream of drivers coming over to it, asking about what just passed them!

A well deserved thumbs up after 25 hours of endurance racing.

Ride along with racer John George as he races in the 2010 25 Hours of Thunderhill.

February 24, 2026

Congratulations to Dave E. on graduating his ’33 Hot Rod build!
